out the triangle on the page in your handout.
Be careful...try to keep the remaining sheet of paper in one piece.
First examine the arrow on the
triangular-shaped plate A showing the direction of relative plate motion with respect to
plate B (plate B is the piece of paper surrounding plate A -- the one with
a hole in it).
Put the triangular piece of paper of Plate
A -- back into the hole (exactly into hole) -- once it is in its proper
place, move plate A in the direction of the arrow.
Using the plate motion, write the name of the type of plate boundary
along each boundary that surrounds plate A
The animation at the left shows, the
same thing as your cutout, the "relative plate motion" of plates A and B, meaning the motion of one plate,
plate A, relative to another plate, so at least two plates are involved!!!
In this problem, plate B is considered stationary and A is moving, but it
could be just the opposite, plate B could be thought as moving and plate A fixed -- all
depends on your point of view!
